Hmm... well, don't spout off BS about things you know little to nothing about, or people who do will call you on it. It's simple. Or when you do, just roll with it, don't get all butthurt when people recognize your bluster.
You're right, I know little about how I would react in a completely hypothetical situation. I mean, afterall, I'm the one who's taking an innocuous one-line sentence and jumping around on Tom Smykowski's Jump To Conclusions mat with a big-ass chip on my shoulder. Oh, wait. That's not me. That's you!
